failure of a fuel pump housing electrical connector if applicable. The existing AD also

requires the deactivation of certain fuel tanks or fuel pumps and the installation of

housing electrical connectors with new, improved parts, which would temlinate the AF

revisions, deactivation of certain fuel tanks and fuel pumps, and placard installation. T
